200个GeV < sqrt{s} < 7 TeV的多重数、平均p_T和p_T分布的饱和度和标度

Saturation and Scaling of Multiplicity, Mean p_T and p_T Distributions from 200 GeV < sqrt{s} < 7 TeV

Larry McLerran, Michal Praszalowicz

摘要:

最近在LHC实验中测量了多重数、平均横动量和带电粒子横动量分布。多重数和平均横动量随束流能量的增加而增加。这种增长在彩色玻璃凝聚体理论中是预期的,该理论将饱和物理学纳入胶子分布的演化中。我们表明,能量依赖的$p\overline{p}$数据和LHC数据$pp$散射在\sqrt{s} > 200 GeV可以简单地描述使用最少量的模型输入。这种描述使用的参数与HERA和RHIC实验数据的彩色玻璃冷凝物描述一致。

英文摘要:

The multiplicity, average transverse momentum, and charged particle transverse momentum distributions have recently been measured in LHC experiments. The multiplicity and average transverse momentum grow with beam energy. Such growth is expected in the theory of the Color Glass Condensate, a theory that incorporates the physics of saturation into the evolution of the gluon distribution. We show that the energy dependence of the $p\overline{p}$ data and the LHC data for $pp$ scattering at \sqrt{s} > 200 GeV may be simply described using a minimal amount of model input. Such a description uses parameters consistent with the Color Glass Condensate descriptions of HERA and RHIC experimental data.
